I had worked at the university for a lot of years, and was no spring chicken at forty. My work frequently had me all over my department, doing all sorts of work, some of it fairly dirty. I tried to stay on good terms with the rest of the staff, including the custodial staff, particularly because I was prone to making messes when I worked on equipment.
We had a new custodian in the building, Tina. She was in her early thirties, fairly slim, very pretty, and oh yes, had a nice large pair of tits, which have always been my favorite part. She traditionally wore jeans and baggy t-shirts at work, which I frequently joked with her "hid her best assets". Initially I was afraid of sexual harassment, but it was clear from her returned jokes and comments that as long as we kept it between us and not in front of others, that there was no problem. It was not unusual for her to joke when she came into my office to dump the trash late in the morning. One day I was crawling around the floor under my work tables looking for a tiny nut that I dropped.
"Whatcha doing down there?" I heard her ask from behind me.
"Looking for a nut."
"OH? Did you lose one? Seems like they're both there!" she kidded.
I crawled out from under the table and looked up at her. "I'd ask you to come down here and help, but I'm not sure you could get close enough to the floor with those huge hooters to be able to help."
"Never know what I can do with these babies!" she replied with a huge grin as she hefted one of her tits in its industrial strength bra.
"Any time you want to demonstrate!" I said as I crawled back down to look for the tiny piece of hardware.
"Someday I just might!" she chided as she put an empty liner in my trash can.
"Promises promises." I said over my shoulder
"See you tomorrow!" she said before heading out of the office door. Eventually I found the errant nut and got the project assembled.
That was pretty much a normal type of conversation if we were alone. All in fun.
Things changed one day. As I frequently had to work on engines and such, I always kept grubby work clothes around to change into. My office was L shaped, since part of it extended around behind an equipment closet. It was common for me to lock my office door and then step back into the L portion where I wasn't visible through the office window and quickly change clothes, either putting on or taking off the grubby portion. I had probably done this a hundred times with no problem. That particular day, like many others, I locked the door and stepped back to change into my grubbies before going to work in the engine lab. I had just finished pulling off my shirt and shoes and was standing with one leg in and one leg out of my pants, wearing nothing except my socks and my skimpy underwear.
When my wife was amorous around the middle of the month, she would make sure to put some sexy satiny bikini underwear on top of my underwear drawer. She knew that by the time I wore those all day I would be horny and ready to meet her needs. In reality I didn't need much revving up to have sex with her. All she had to do was take off her shirt and bra and I was ready to strip down and have sex any time, any place. But it seemed to make her feel good that I thought about her all day. It also had the effect of making me somewhat larger after having a hardon a good part of the day. That day was no exception. I was wearing a pair of very brief bright red men's bikini underwear, with the bulk of my persistent hardon poking over the top. The tiny underwear barely covered my dick and balls when I was soft. When I was hard, like now, better than two thirds of my dick stuck out the top.
I didn't hear the lock in the door click, and apparently didn't hear it open. What I did hear was a gasp just before the door clicked closed, with me standing with one leg in and one leg out of my pants. Tina had stepped to my office to dump the trash, thinking I wasn't in, but instead of dumping the trash she was standing there, frozen, staring with a shocked look at me standing there half naked. She stood looking at me for several seconds, with me frozen, not reacting or acting. I felt like my brain had gone numb all of a sudden. Finally the silence was broken as she gave a short whistle in appreciation of the view of my dick.
"Don't let me interrupt." She said with a huge grin.
"I appreciate that." I said as I finished pulling my pants off and tossing them across a chair. I leaned over to pick up my grubby pants and then moved to put them on.
"Not taking any more off?" she said with a fake pout.
"You'd like that wouldn't you." I teased back. Why don't I just strip naked so you can get a good look."
"Would you?" she grinned.
"Sure! I'll just stand here and let you get a good long look too!" I said only half joking as I hooked my thumbs into the top of my underwear and standing there like that.
"Well, what are you waiting for?" she asked as she stepped around my desk and sat in my chair.
"You're serious?"
"Why not?" she said as she turned my chair so the back was to the window. "Will this help?" she asked as she pulled the top of her shirt up so I could see her bra enclosed tits. "Or maybe this!" she added grabbing the bottom of her bra and pulling it up so her 38 DD tits were on full display. They were full and round with dark areola about three inches across and nipples that were easily half an inch in diameter and sticking out at least that far. She was obviously very turned on.
"Why not!" I echoed as I pushed my underwear down to my knees and stood back up.
"Wow! Nice cock!" she said as my dick swung and bobbed.
"Thanks! Nice tits."
"You like em?"
"What's not to like?" I asked her as she ran her fingers around her hardening nipples.
"You like tits?"
"My favorite part."
"OH? She asked looking over at me. "You don't like pussy?"
"That I never said!"
"Take them the rest of the way off and I'll show you mine!" she said as she unsnapped her pants.
What the hell, I thought to myself. I bent over and pushed them the rest of the way down and stepped out of them, leaving me in nothing but my socks while she rolled my desk chair around into the L with me, so she wouldn't be visible to the window. She stood up and pushed her pants down to her knees and then sat back down, pulling her shirt back up over her tits again. I could see everything she had to offer from her tits to her knees. She was slim, as I had figured, probably not over one forty. She had a completely shaved pussy with slightly protruding dark lips, glistening with moisture.
"What do you think? Do you like my pussy?" she asked as she lifted and spread her legs as far as her pants would allow.
"What's not to like!"
"I'm glad you like it." She said rolling the chair toward me. "Because I really like how you cock looks." She said quietly as she reached out and gripped it with her hand. She squeezed its hardness a few times, stroking her hand up and down before pulling her whole body toward it and sucking the end into her mouth. I groaned involuntarily as she suctioned my dick all the way into her throat, making my dick twitch and grow even more.
"Oh you like that too!" she cooed after pulling my dick from her mouth. She let go of me long enough to pull her shirt and bra off the rest of the way and then lean back in to suck my dick. She sucked like a pro, working both her hand and mouth on my hard dick. I hadn't planned this, and wasn't really planning on cheating on my wife, but this had taken on a life of its own, and now all I was thinking with was hormones.
I moaned as she brought me closer to climax. "I'm going to cum." I said between clenched teeth.
She pulled my dick from her mouth and started stroking it franticly, rubbing her hand in a circle around the head each stroke.
"Good! I want you to. I want you to squirt all over my huge tits! I want to feel your hot gooey cum squiring all over my tits. I wanted that for months now!" she panted.
"ohhhhhhh" I moaned as the first shot of cum flew from the end of my dick, hitting her at the base of the neck. She aimed my hose so that the successive shots hit all over her tits, sliding and running down and across her nipples, and eventually dripping into her lap. When I stopped spurting and had reduced to a drool she sucked my dick back into her mouth, and sucked it no hands, draining it of the last of its juice. Her hands were busy rubbing my cum all over her tits, massaging it in like lotion. Finally my dick softened and she let go, leaning back in my chair. I could see beads of moisture on her pussy lips and knelt down, pushing her legs apart. I licked up her lips, tasting her sweet nectre. I licked a second time, spreading her lips with my tongue and dragging it across her engorged clit.
"Oh god yes" she hissed as she squeezed and pinched her nipples.
I licked a third and fourth time before concentrating on just her clit. Her body shook and spasmed as her orgasm washed over her only a few moments later, her breath coming in ragged gasps as I continued to flick her clit with my tongue. She finally pushed my head away from her pussy and cried. "No more... please!"
I wiped my mouth with a paper towel and then started pulling on my clothes, covering my dick first with the red underwear and then my pants. She was just starting to stand up and pull her pants up when I pulled my shirt on and started working on my shoes. I sat down to tie my shoes, which put my head at tit level, as she wiggled her tits around while getting dressed. She did her shirt and bra last, wanting to give me the longest look possible. Then she leaned down and kissed me on the lips gently.
"Thank you that was wonderful"
"You're welcome." I answered as I got up to follow her out of the office.
The next several days were interesting. It seemed to me that the sexual innuendo ratcheted up significantly, even though the two of us talked after that and agreed that we were both married and didn't want to screw that up, so we were not going to repeat it. One day I was headed up in the elevator and I heard her call to hold the elevator, which I did. The car started up, and it's a SLOW elevator....
"So seen any good tits lately?" she asked me as she leaned against the side of the car.
"Not really." I answered
"How about these?" she asked as she pulled the front of her shirt up, and exposed her tits to me. Instead of the industrial sports bra she had worn last time I saw her, this time she had on a lacy bra that held her tits up, but stopped below the nipples, leaving them and the whole top of her tits exposed.
